LOCK-HINGE.

SPECIFICATION forming part of Letters Patent No. 403,570, dated May 21, 1889.

Application filed August 17, 1888. Serial No. 282,951. (No model.)

To all whom it may concern.-

Be it known that I, J OSEF XVOLF, of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Lock-Hinges, of which the following is a specification.

This invention relates to lock-hinges more especially designed for fastening windowshutters and holding them in place.

In the accompanying drawings, Figure l is an elevation of my improved shutter-fastener, the shutter being closed. Fig. 2 is a plan view of the same, the shutter being closed and parts of the shutter and window-frame being in section. Fig. 3 is a sectional plan View of my improved shutter-fastener, the shutter being open. Fig. 4 is a side View of the same, the shutter being open, parts being broken away, and others shown in dotted lines.

Similar letters of reference indicate corresponding parts.

The hinge plate A is provided with a bracket, B, the vertical plane of which is at an angle to face the plate A, and from the top of said bracket the hinge-pintle 0 projects upward.

The hinge plate D is provided with a bracket, E, the longitudinal plane of which is also at an angle to the face of the plate D, and on said bracket the socket F is formed for receiving the pintle C. The upper surface of the bracket B and the lower surface of the bracket E are made flat and smooth. On the top of the bracket E the tubular socket G is formed for a vertically-sliding bolt, H, provided with a head, H, having a laterally-proj ecting arm, E, that enters an aperture in the outer end of a lever, I, pivoted in the recess or countersink J, in the inner edge of the shutter J, the inner end of said lever I being bent and formed with a finger-plate, I Below the inner end of the lever I a latch, K, is pivoted, which,.when raised, rests against the bottom edge of the inner end of the lever I and prevents pressing down said lever, thus preventing raising the bolt H. The bracket E is provided with the two opposite straight edges, a and Z7, and the bracket B is provided on its upper face near its inner edge with shoulders d h, which form an obtuse angle, the former serving as a stop for the straight edge a of the bracket E when the blind is opened, and the latter as a stop for the straight edge I) of the bracket E when the blind is closed. Said bracket B is also provided at opposite sides of the pintle O with the two opposite notches, m and 0, the inner parts of which are rounded, or so shaped that the bolt H can fit snugly against them.

The hinge-plate A is fastened, by means of screws or otherwise, to the window-frame M, and the plate D is fastened to the shutter J.

The operation is as follows: hen the shutter is closed, the rounded edge of the notch 0 in the bracket B registers with one side of the bore of the socket G, and the bolt H rests in and against the sides of the recess 0, thus looking the parts in place. hen it is desired to open the shutter, the inner end, I of the lever I is depressed, whereby the outer end is raised, and thereby the bolt H is withdrawn from the notch 0 and raised sufiiciently to clear the top of the bracket B. The shutter is then opened slightly, the lever I released, and the bolt 11 descends until itrests upon the top of the bracket B. If,- then, the shut ter is opened entirely, the bottom of the bolt H slides over the top of the bracket B until it arrives at the notch or recess m, into which it drops, thus locking the shutter in place in the open position. The edge a of the bracket E now rests against the shoulder d of the bracket B and prevents swinging the shutter too far toward the wall, and also relieves both the bolt H and pintle O of undue strains in case the wind rattles or acts upon the shutter. To close the shutter, the finger-plate I of the lever I is again depressed for the purpose of raising the bolt H, the shutter is closed, and when the bolt H arrives at the notch oit drops into the same, and thus locks the part in place.

\Vhen the shutter is closed, the edge I) of the bracket E rests against the shoulder h of the bracket B, thus assisting in holding the shutter in place and relieving the pintle and bolt of undue strains.

Having thus described my invention, I claim as new and desire to secure by Letters Patent In a lock-hinge, the combination, with a hinge-plate, of a bracket thereon provided with a pintle, two opposite notches, and angular shoulders on its upper face, a hinge- In testimony that I claim the foregoing as plate provided with a socket for the hingemy invention I have signed my name in prespintle, an additional socket and two straight ence of two subscribing witnesses.
